Systems and methods for filtering unsafe content at a network security appliance are provided. According to one embodiment, a network security appliance captures network traffic and extracts a media file from the network traffic. The network security appliance then determines the presence of a hidden data item embedded in the media file in a machine-readable form. When such a hidden data item is identified, the network security appliance performs one or more actions on the media file based on a predefined security policy.
